1.2测试太原总公司和北京分公司的连通性
1.2.1北京分公司到总公司的流量
BJ#ping 172.16.10.1 source 172.16.11.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.10.1, timeout is 2 seconds:
Packet sent with a source address of 172.16.11.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/59/88 ms

1.2.2太原总公司到北京分公司的流量
inside#ping 172.16.11.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.11.1, timeout is 2 seconds:
